Crank Up The Juice On A Cheap Laser Pointer

If you're looking to have a little weekend science-lab fun with lasers it turns out that in the heart of every cheap laser pointer is a fire-starting, balloon-popping, monster.

What's the secret to upgrading your cheap laser from a boring presentation tool to a goggles-on-for-safety experiment? Over at Wired's How-To wiki they detail how to take apart a cheap laser pointer and find the adjustable variable-resistor on the circuit board inside. Tweak that resister with a small jeweler's screw driver and you can crank the juice up on your laser pointer—not too far or you'll burn it out! Visit the wiki at the link below for full instructions.

Inspired by the potential burnination of your cheap laser? Have a warranty-voiding bit of fun to share? Lets' hear about it in the comments. Oh, and please be careful, and proceed at your own risk.

Amp Up a Laser Pointer [Wired How-To Wiki]


    Errr... apart from this not working... all you end up with a DEAD laser pointer. The varistor is there for a good reason.

    It seems to be in direct contravention of police efforts to curb "powerful" laser pointers

    This strikes me as a wildly irresponsible post. There is no practical reason to soup up a laser pointer that I can think of but there are a heap of dangerous and stupid ones that come to mind.

    Furthermore, does this really qualify as a lifehack? Maybe there's a pyromaniacs blog somewhere where this would be more appropriate.

    Lifehacker, get your act together. Seriously.

    I always wanted a quick way to warm up my coffee. Thanks !!
